First, I had a phone screen with the hiring manager for the role/team I was interviewing for, which lasted 45 minutes. There were some questions about my experience and resume, and also some questions based on Amazon Leadership Principles. I then heard back about 2-3 business days after that I would be proceeding to the "loop." The loop was the most difficult part, because it required a lot of preparation. I had five, one hour interviews, and two thirty minute breaks. Each interviewer asked 2-4 questions based on the Amazon Leadership Principles, and questions about my background and technical skills. 10-15 mins were left per each interview round to ask questions about Amazon, the person's role, etc. I heard back within the five business day guarantee with an offer.

It was fine but nothing special. Typical questions for an intern applying for an internship program. You wouldn't be surprised. Come with good questions. That always helps. Worst case scenario you don't get it.
